INTRODUCTION TO SIZE MEASUREMENT BY DYNAMIC LIGHT SCATTERING (DLS)

Why DLS is suitable for your application

The technique is ideal for the measurement of the size of colloids, nanoparticles and molecules, without requiring agitation to make the sample suitable for analysis. From the size, an estimate of the molecular weight can be made, which has the benefit of being faster to confirm oligomeric state than size exclusion chromatography (SEC).
